具体实施方式 Detailed ways

[0044] 请参照图1,图1示出了本发明一实施例的语音通信装置100的示意图。 [0044] Referring to FIG. 1, FIG. 1 shows a schematic view of a voice communication apparatus of the present embodiment of the invention 100. 在图1中,语音通信装置100包括控制单元110、手持式语音传收器120、位置状态检测器130、开关140以及单向信号传送器150。 In FIG 1, the voice communication device 100 includes a control unit 110, hand-held voice the transceiver 120, position state detector 130, switch 140 and a check signal transmitter 150. 控制单元110用以控制语音通信装置100的整体作动。 The control unit 110 for controlling the entire voice communication device 100 is actuated. 在本实施例中,语音通信装置100可以通过因特网与外界沟通,也就是说,控制单元110可以藉由因特网来传收多种信息。 In the present embodiment, the voice communication device 100 can communicate with the outside world through the Internet, that is, the control unit 110 may transmit a variety of information received by the Internet. 手持式语音传收器120例如是电话的听筒,用来提供使用者手持,并据以进行通话。 Handheld voice transceiver of the telephone handset 120, for example, to provide the user holds, and accordingly make a call. 手持式语音传收器120可以接收使用者所发出的语音,并传送至控制单元110以进行语音信号的编码动作,控制单元110并可将编码后的语音信号发送出去。 The transceiver handheld voice 120 may receive a user voice emitted and transmitted to the control operation unit 110 for encoding the voice signal, the control unit 110 and the coded speech signal is transmitted. 另外,手持式语音传收器120还可包括发送语音的扬声器部份,用来将远端传至的语音信号传送至使用者的耳中。 Further, a handheld voice transceiving portion 120 may further include a speaker voice transmission, for transmitting a voice signal transmitted to the distal end of the user's ear.

[0045] 位置状态检测器130配置在语音通信装置100上,并用来耦接手持式语音传收器120。 [0045] The position of the state detector 130 is disposed on the voice communication device 100, and for coupling the transceiver handheld voice 120. 位置状态检测器130依据手持式语音传收器120的位置状态来产生状态信息,具体来说明,位置状态检测器130可以是挂钩式开关,而其所产生的状态信息可用来指示手持式语音传收器120是否挂靠在位置状态检测器130上。 A position detector 130 according to the state of the hand-held position of the speech state the transceiver 120 to generate the state information, particularly bright, the position detector 130 may be a state of the hook switch, generates the status information may be used to indicate a handheld voice transmission retractor 120 is anchored in the position state detector 130. 也就是说,当状态信息指示手持式语音传收器120是挂靠在位置状态检测器130上时,表示手持式语音传收器120处于闲置的状态,相对地,当状态信息指示手持式语音传收器120并非挂靠在位置状态检测器130上时,表示使用者持取手持式语音传收器120并使用手持式语音传收器120以进行通话。 That is, when the state information indicates that the handheld voice when the transceiver 120 is anchored in the position state detector 130, the speech represented handheld the transceiver 120 is in an idle state, contrast, when the state information indicates that the handheld voice transmission retractor 120 is not anchored in the upper position state detector 130, it indicates that the user holds the handheld voice taking the transceiver 120 and voice transmission using the hand-held retractor 120 to make a call.

[0046] 开关140耦接在手持式语音传收器120以及控制单元110间。 [0046] The switch 140 is coupled handheld receiver 120 and a voice transmission control unit 110. 开关140接收位置状态检测器130所发送的状态信息,并依据状态信息以导通或切断手持式语音传收器120以及控制单元110间的连接路径。 Position switch 140 receives the state information by the transmitter state detector 130, and based on the status information or to turn off the transceiver handheld voice connection paths 120 and 110 of the control unit. 请注意,当手持式语音传收器120是挂靠在位置状态检测器130上时,位置状态检测器130发送相对应的状态信息,并使开关140依据状态信息而切断手持式语音传收器120以及控制单元110间的连接路径。 Note that, when the hand-held transceiver of speech 120 is anchored at a position on the state detector 130, detector 130 transmits the position corresponding to the state of the status information, depending on the state switch 140 and cut off the handheld voice information the transceiver 120 and a connection path between the control unit 110. 如此一来,在当手持式语音传收器120闲置的状态下,手持式语音传收器120是无法传送语音信号至控制单元110中的。 Thus, in the voice transmission when the hand-held retractor idle state 120, the voice transceiver of a handheld 120 is not transmitting voice signal to the control unit 110. 也就是说,黑客无法通过侵入并操控控制单元110来由手持式语音传收器120接收语音通信装置100所在位置的声音以进行窃听。 That is, hackers can not invade and by manipulating the control unit 120 receives a sound 110 reason voice transceiver of a handheld voice communications device 100 to perform tapping location.

[0047] 在另一方面,当手持式语音传收器120被使用者持取后,位置状态检测器130变更其所发送状态信息,并使开关140依据状态信息而导通手持式语音传收器120以及控制单元110间的连接路径,使使用者发出的语音可以通过被导通的开关140传送至控制单元110以进行正常的通话。 [0047] On the other hand, when the hand-held transceiver of speech 120 is held by a user to take a position detector 130 changes the state of its transmit status information, based on the state information and switch 140 is turned on handheld voice transceiving a control unit 120, and the connection path 110, so that the voice uttered by the user may be 110 for normal calls transmitted by the switch 140 is turned on to the control unit.

[0048] 值得一提的是,本实施例中,语音通信装置100还包括单向信号传送器150被配置在位置状态检测器130以及控制单元110间。 [0048] It is worth mentioning that, in this embodiment, the voice communication device 100 further comprises a unidirectional signal transmitter 150 is disposed at a position detector 130 and a state control unit 110. 单向信号传送器150仅提供单方向的信号传输功能,其中,图1中的单向信号传送器150可将位置状态检测器130所产生的状态信息传送至控制单元110中。 Unidirectional signal transmitter status unidirectional signal transmitter 150 in one direction only to provide signal transmission function, which, in the position of FIG. 1 150 may be generated by the state detector 130 transmits the information to the control unit 110. 而控制单元110并不能通过单向信号传送器150发送信号至开关140以控制开关140的导通或断开状态。 And 110 and the control unit can not be uni-directional signal transmitter 150 sends a signal to switch 140 to control the state of the switch turned on or off 140. 如此一来,开关140将可以与控制单元110完全隔离,而不致于被黑客操控以进行窃听。 Thus, switch 140 will be completely isolated from the control unit 110, it would not be manipulated by hackers to eavesdrop.

[0049] 以下请参照图2,图2示出了本发明另一实施例的语音通信装置的示意图。 [0049] Referring to the FIG. 2, FIG. 2 shows a schematic diagram of the voice communication apparatus according to another embodiment of the present invention. 在图2中,语音通信装置200包括控制单元210、手持式语音传收器220、位置状态检测器230、开关240及270、单向信号传送器250、语音传收器260以及警示信号产生器280。 In FIG. 2, the voice communication device 200 includes a control unit 210, hand-held voice the transceiver 220, position state detector 230, switch 240 and 270, one-way signal transmitter 250, the transceiver 260 and a voice alarm signal generator 280. 开关270耦接在语音传收器260与控制单元210间。 Voice switch 270 is coupled in the transceiver 260 and the control unit 210. 开关270接收由控制单元210传送的控制信号CTRL,并依据控制信号CTRL以导通或断开。 Switch 270 receives a control signal CTRL transmitted from the control unit 210, and according to a control signal CTRL to turn on or off.

[0050] 此外,在本实施例中,警示信号产生器280耦接至控制单元210,并且,警示信号产生器280接收控制单元210所传送的控制信号CTRL。 [0050] Further, in the present embodiment, the warning signal generator 280 coupled to the control unit 210, and the warning signal generator 280 a control signal CTRL unit 210 transmits the received control. 警示信号产生器280并依据控制信号CTRL来决定是否发送出警示信号,具体来说明,当开关270依据控制信号CTRL而导通时,警示信号产生器280可同时依据控制信号CTRL发送出警示信号。 Warning signal generator 280 and according to a control signal CTRL to determine whether to send a warning signal, particularly clear, when the switch 270 according to the control signal CTRL is turned on, the warning signal generator 280 can simultaneously transmit a warning signal according to a control signal CTRL. 相对的,当开关270依据控制信号CTRL而断开时,警示信号产生器280可同时依据控制信号CTRL不发送出警示信号。 In contrast, when the switch control signal 270 based on the CTRL disconnected, the warning signal generator 280 can not simultaneously transmit a warning signal according to a control signal CTRL.

[0051] 请注意,本实施例的语音传收器260可以是语音通信装置200上除手持式听筒外,任一可以接收语音信号的元件。 [0051] Note that, the voice the transceiver 260 of the present embodiment may be a handheld receiver element addition, any one can receive a voice signal on a voice communication device 200. 并且,语音传收器260的数量也不受限于一个。 Further, the number of voice the transceiver 260 is also not limited to one. 多个语音传收器同样可以实施于本发明的语音通信装置上,各语音传收器对应配置一个开关及一个警示信号产生器,各警示信号产生器会依据对应的开关的导通或断开状态来决定是否产生警示信号。 The transceiver plurality of speech can also be implemented on a voice communication apparatus according to the present invention, the transceiver of each voice switch and a configuration corresponding to a warning signal generator, each signal generator warning will be based on the corresponding switch is turned ON or OFF state to decide whether to generate a warning signal.
